During the last week Chandra completed the observing schedule as
planned.

Real-time procedures were executed on Feb 12 and 14 to monitor
thruster performance during scheduled angular momentum unloads. The
enhanced monitoring is in response to a recent downward trend in the
specific impulse on MUPS thruster A1. This trend remains under
investigation to determine whether it is simply an indication of
normal thruster degradation, unanticipated behavior in an elevated
thermal environment, or an early warning flag of a more serious
condition.

A Chandra press release was issued on Feb 13 as a NASA press release
describing observations of W49B, a highly distorted supernova remnant,
produced by a rare type of explosion. There is evidence that W49B left
behind a black hole - not a neutron star like most other
supernovas. If confirmed, W49B would be the most recent black hole
formed in our Galaxy. For details see:

The schedule of targets for the next week is shown below and includes
an observation of GRB 121027A, which was accepted as a Target of
Opportunity on 2012 Dec 7, and an observation of MAXI J0556-332, which
is a follow-up to a Target of Opportunity accepted on 2012 May 8.
